Abstract: A method of predicting colors resulting from using one ink on a printer. The method includes the steps of: producing a test page for the printer, the test page having a plurality of sample ink patches, each patch having a plurality of ink dots according to a predetermined ratio for each patch, the predetermined ratios being based on a number of dots printed for a corresponding patch compared to a maximum number of dots; measuring each of the sample ink patches to produce a plurality of color space coordinates for each patch; and fitting values representing a number of dots for each patch and color space coordinates to a plurality of predetermined functions using a minimization process in order to predict the colors.

Abstract: Disclose are various methods for optimising conversions between color spaces (FIG. 1). A set of atomic mathematical ((a)-(f)) functions are identified which, when performed in sequence, implement the conversions. Specific (first) sequences of the mathematical functions are then identified which when preformed convert colors between particular color spaces. A set of computational operations ((g)-(i)) are then established for evaluation using a computing device, the operations, when performed in (second) sequences cause the color conversions. A particular one of the first sequences required for converting from a first color space to a second color space is then identified and transformed into a (third) sequence of computational operations chosen from the computational operations ((g)-(i)) having substantially the same transformation effect as the particular sequence. Also disclosed is a method of sequentially combining a first color conversion list (FIG. 2A) with a second color conversion list (FIG.
